Combine with an AI-301DA and LS-301 speakers to create a compact Hi-Res systemThe PD-301 can be combined with an AI-301DA pre-main amplifier (also from the 301 Reference Series) that has a USB DAC and allows aptX® Bluetooth input. Together they form a compact high-resolution system that allows USB audio input from a computer and wireless playback from smartphones and tablets while also supporting CDs and USB flash drives as well as a wide range of FM frequencies.

Combine with a UD-301 for a high-precision CD player system By connecting this model digitally to a UD-301, which is a USB DAC with a dual mono structure in the same 301 Reference Series, you can upconvert the PCM 44.1kHz/16-bit digital data of your CDs to 192 kHz. By conducting D/A processing after converting to a higher-precision digital signal, a smoother analog signal can be output. Furthermore, in addition to RCA unbalanced outputs, the UD-301 has XLR balanced outputs, so it is possible to incorporate it into a more advanced system with a hi-fi amplifier that has balanced inputs.Slot-in CD drive mechanism that enables quick loading and automatic playbackThe CD drive utilizes a compact high-precision slot-in CD drive mechanism. The drive, which was designed especially for audio and has a record of being used in professional equipment, is capable of loading quickly. The automatic playback function, which automatically starts playback after a CD is loaded, allows you to enjoy music soon after inserting the CD into the slot.

Supports playback of MP3, WMA, AAC and WAV filesWAV (USB only), AAC (USB only), MP3 and WMA files can be played back from USB flash drives and CD-R and CD-RW discs. The song name and artist can be shown on the unit's display during playback of MP3, WMA and AAC files.* (Notes: This is only possible when files have ID3 tags.)

High-precision digital- audio converterA Burr-Brown PCM5142 D/A converter, which has an established reputation and is made by Texas Instruments, is used to convert the digital audio signals read from CDs and USB flash drives to analog.

Coaxial and optical digital outputs also allow digital output of FM broadcastsIn addition to analog outputs, coaxial and optical S/PDIF digital outputs (one each), which are used widely, are built-in. By connecting an AI-301DA, UD-301 or other component that is capable of S/PDIF digital input, you can also use this unit as a transport that transmits pure digital signals. By using a D/A converter that is even higher precision, you can enjoy listening to your favorite CDs with an even higher level of audio quality. Furthermore, audio received with the FM radio tuner can also be output as S/PDIF digital signals.(Note: Digital output is at 44.1 kHz/16-bit regardless of the playback format and source.)

FM tuner supports RDS（UK/Europe Model only）The Radio Data System (RDS) is a broadcasting service that allows stations to send additional information along with the regular radio program signal.

Model PD-301DAB including DAB tuner

Solid aluminum body and compact installation spaceAluminum panels have been used for the exterior. While maintaining the elegance of a traditionally styled hi-fi component, the all-metal chassis provides a solid body with excellent vibration control, minimizing the effect of vibrations on audio quality. With the 501 Series, we advanced the concept of compact high-performance audio devices that can be placed even on desktops, and we have further developed this with the 301 Series. The body, which has been restricted to a width of 215 mm, enables even greater freedom of placement

Included remote control with number pad convenient for selecting tracksA remote control with a number pad that is convenient for selecting tracks is included. The AI-301DA remote can also control the basic functions of the PD-301.
